The aim of this study was to determine changes in cognitive function, markers of physiological resilience, and running performance during a backyard\u2010running event. Twelve male ultrarunners (38\u00a0\u00b1\u00a08\u00a0years old, BMI: 23.5\u00a0\u00b1\u00a01.6\u00a0kg\/m\n                    <jats:sup>2<\/jats:sup>\n                    , and VO\n                    <jats:sub>2max<\/jats:sub>\n                    : 60.8\u00a0\u00b1\u00a04.7\u00a0mL\/min\/kg) were monitored before, during, and after the event. Cognitive performance was determined using a cognitive test battery before, during, and after the event. During the event, the rating of perceived exertion (RPE), blood lactate concentration, and heart rate (HR) were assessed. Physical performance was investigated using the total number of completed laps and running speed per lap. Athletes completed 34\u00a0\u00b1\u00a017 laps equaling 227.8\u00a0\u00b1\u00a0113.9\u00a0km with average speeds starting at 9.0\u00a0km\/h and slowing down to 7.5\u00a0km\/h at the end of the event. Physiological resilience (estimated using HR\/speed) varied between athletes, with significantly lower values in the more proficient backyard runners at the end of the event (\n                    <jats:italic>p<\/jats:italic>\n                    \u00a0&lt;\u00a00.05). HR and lactate levels remained constant, whereas a progressive increase in RPE was noticed (\n                    <jats:italic>p<\/jats:italic>\n                    \u00a0\u2264\u00a00.001). A significantly worsened reaction time was observed for several cognitive tasks after the event compared to baseline measures (\n                    <jats:italic>p<\/jats:italic>\n                    \u00a0\u2264\u00a00.05). These observations show that physiological resilience differs depending on the level of endurance performance of the athletes. Furthermore, the backyard ultrarunning event negatively impacted psychomotor speed. Therefore, the results suggest that implementing strategies that enhance physiological resilience and\/or psychomotor speed could potentially have a positive effect on performance in ultraendurance activities.\n                  <\/jats:p>","DOI":"10.1002\/ejsc.12190","type":"journal-article","created":{"date-parts":[[2024,9,14]],"date-time":"2024-09-14T11:34:43Z","timestamp":1726313683000},"page":"1432-1441","source":"Crossref","is-referenced-by-count":12,"title":["Backyard running: Pushing the boundaries of human performance"],"prefix":"10.1002","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6901-7199","authenticated-orcid":false,"given":"Kevin","family":"De Pauw","sequence":"first","affiliation":[{"name":"Human Physiology and Sports Physiotherapy Research Group (MFYS) Vrije Universiteit Brussel (VUB)  Brussel Belgium"},{"name":"Brussels Human Robotics Research Center, BruBotics Vrije Universiteit Brussel (VUB)  Brussel Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Ampe","sequence":"additional","affiliation":[{"name":"Human Physiology and Sports Physiotherapy Research Group (MFYS) Vrije Universiteit Brussel (VUB)  Brussel Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Y.
